TO ALL WHOM IT MAY CONCERN:

Be it known that we, HERMAN ROYER andIOUIS ROYER, of San Francisco city, San Francisco county, State of California, have invented a new and improved Machine for Converting Raw Hides into Leather; and we do hereby declare the following description and accompanying drawings are snfiicicnt to enable any person skilled in the art or science to which it most nearly appertains to make and use our said invention or improvements without further invention or experiment.

The nature of our inventionis to provide an improved machine for converting ,raw hides into leather, of I that class which is used for belting, lacings, and other purposes where it is n'ccessary to preserve the native strength and toughness without destroying or impairing the natural fibres or grain of the leather. Q In order 'to accomplish our object, we employ a machine mounted ona suitable frame, having a vertical F'- slotted shaft, to which is attached," at its base, a bevelled wheel between two bevelled pinions upon a horizontal shaft. Around the vertical shaft is placed crew of vertical pins or rollers, held in place by upper and lower rings, one of which is firmly bolted to the frame. -s

An iron weight or press is employed for .crowding the coil of hide down after it has received the forward and back action around the shaft.

- To more fully illustrate and describe our invention, reference is bad to the accompanying drawings, of which- Figure 1 is a horizontal section through A B.

Figure 2, aside sectional elevation, showing central shaft.

Figure 3, a. side sectional elevation.

Figure 4, a horizontal section, showing the hide around the shaft in the circle of pins.

A represents the frame, of any suitable materials, up thronghwhich the vertical shaft B passes, having a slot, B, through which the end of the hide is placed/where it is'held in place by the set-screws b b 6 I1.

C C are vertical pins or rollers set in the rings D and D, the lower one, or D, being firmly attached to the frame by bolts c c. t i

Abevelled wheel, E, is attached to the vertical shaft 13, which is actuated by the bevelled pinions F F placed on the horizontal driving-shaft G. This shaft has a pulley, H, for driving the machine An iron weight, I, having an opening through-its centre for the vertical shaft, and verticalgrooves, 1." 2', in it to prevent its turning, is .placed upon the inside of the pins or rollers, and, by pressing upon this weight, the hide is compressed edgcwise, after the forward and backward stretching or pressing is performed lengthwise.

The operation of our machine isasfollews: The end of the raw hide, after it has been deprived of the hair, is introduced into the slot B, and the set-screws 11,56 turned against it, when motion is imparted to the machine, and the hide is wound tightly around the vertical shaft. 'Whcnthis is accomplished, and suificient time has elapsed, theshaft is slowly'reversed by throwing the other pinion into gear, when the hide commences to uncoil, or doubling back from the shaft, which, with the folding back, and pressing against the pins or rollers, produces the desired'rcsult of stretching in one way, compressing, corrugating, or roughing. in the opposite direction, when the weight Iis placed upon the top of the hide, and is pressed downward, which, in a measure, compensates for the' stretching lengthwise.

The hide so operated upon is then treated with oil and tallow in the usual way.

By thus treating the hide in our machine, the leather is rendered very tough, and the fibres or grain are ,fnotinjured, but imparts to it a rough, corrugated, and searny appearance, making lC lilOl'c strong and lasting, l r the purposes designed than by any other machine or process. i r Having thus described our invention, what we claim, and desire to secure by Letters Patent, is"

1. The vertical shaft 13 with a slot, 13, and set-screws, b b b, said shaft having a forward and back motion, substantially as and for the purpose described.

2. The pins or rollers CC C setin the rings D and D', together with the grooved weight I, substantiallyas and for the purposes described. i

I In witness whereof, we have hereunto set our hands and seals.
